“We couldn’t be happier with the transformation. Chris and his team managed the entire process with professionalism and attention to detail from start to finish.
The old system was unreliable and constantly causing problems, but the new heat pump and hot water setup have been incredible — quiet, efficient, and perfectly balanced across every floor.
What really stood out was the communication — we always knew exactly what stage the project was at, and the quality of the installation speaks for itself.
Sable Projects delivered exactly what they promised: craftsmanship, care, and genuine pride in their work.”
